It is the responsibility of the manufacturer of a machine or plant to ensure the correct functionality of the entire machine or plant. he safety switchgear must be exclusively used in accordance with the versions listed below or for the applications authorised by the manufacturer. Detailed information regarding the range of applications can be found in the chapter "Product description". 1.5 General safety instructions he user must observe the safety instructions in this operating instructions manual, the country-specific installation standards as well as all prevailing safety regulations and accident prevention rules. Further technical information can be found in the Schmersal catalogues or in the online catalogue on the Internet: he information contained in this operating instructions manual is provided without liability and is subject to technical modifications. here are no residual risks, provided that the safety instructions as well as the instructions regarding mounting, commissioning, operation and maintenance are observed. 1. Warning about misuse In case of improper use or manipulation of the safety switchgear, personal hazards or damages to machinery or plant components cannot be excluded when safety switchgear is used. he relevant requirements of the standard ISO must be observed. 1

2 Solenoid interlock AZM 11../ Exclusion of liability We shall accept no liability for damages and malfunctions resulting from defective mounting or failure to comply with this operating instructions manual. he manufacturer shall accept no liability for damages resulting from the use of unauthorised spare parts or accessories. For safety reasons, invasive work on the device as well as arbitrary repairs, conversions and modifications to the device are strictly forbidden; the manufacturer shall accept no liability for damages resulting from such invasive work, arbitrary repairs, conversions and/or modifications to the device. 2. Product description Manual release (for set-up, maintenance, etc.) he manual release is realised by turning the triangular key (M5 triangular key available as accessory), so that the locking bolt is pulled into the unlocking position. Please ensure that jamming by external influence on the actuator is avoided. he normal locking function is only restored after the triangular key has been returned to its original position. After being put into operation, the manual release must be secured by installing the plastic cover, which is included in delivery. Lateral manual release Manual release on the cover side or on the rear side (ordering suffix -ED/-EU) 2.1 Ordering code his operating instructions manual applies to the following types: AZM 11 ➀-➁➂ K➃-➄/➅-➆➇ No. Option Description ➀ CC Cage clamps SK Screw connection S Connector plug M 12 ➁ 11/03 1 NO / 4 NC with connector plug 11/12 2 NO / 3 NC with connector plug 12/03 1 NO / 5 NC 12/11 2 NO / 3 NC with connector plug 12/12 2 NO / 4 NC ➂ Latching force 5 N R Latching force 30 N ➃ A ➄ Lateral manual release ED Manual release on the cover side EU Manual release on the rear side ➅ Lateral emergency exit D Emergency exit on the cover side U Emergency exit on the rear side N Emergency release ➆ 024 U s 24 VAC/DC 110/230 U s 110/230 VAC ➇ Without LED G With LED riangular key K-M5 ( ) available as accessory. Emergency release (ordering suffix -N) (Mounting and actuation only outside of the safety guard) he emergency release should only be used in an emergency. he solenoid interlock should be installed and/or protected so that an inadvertent opening of the interlock by an emergency release can be prevented. he emergency release must be clearly labelled that it should only be used in an emergency. he label can be used that was included in the delivery. o activate the emergency release in case of an emergency, the orange lever must be turned to the stop in the direction marked by the arrow. In this position, the safety guard can be opened. he lever is latched and cannot be returned to its original position. o cancel the blocking condition, the central mounting screw must be loosened to such extent that the lever can be turned back into its original position. he screw must then be re-tightened. Only if the information described in this operating instructions manual are realised correctly, the safety function and therefore the compliance with the Machinery Directive is maintained. 2.2 Special versions For special versions, which are not listed in the order code below 2.1, these specifications apply accordingly, provided that they correspond to the standard version. 2.3 Destination and use he solenoid interlock has been designed to prevent in conjunction with the control part of a machine, movable safety guards from being opened before hazardous conditions have been eliminated. Interlocks with the power to lock principle may only be used in special cases after a thorough evaluation of the accident risk, since the guarding device can immediately be opened on failure of the electrical power supply or when the main switch is opened. Emergency exit (Fitting and actuation only from within the hazardous area) o activate the emergency exit of the version in case of an emergency, the orange lever must be turned to the stop in direction marked by the arrow. he emergency exit function of the D and U versions is activated by pressing the red pushbutton. In this position, the safety guard can be opened. he blocking condition is cancelled by turning the lever in opposite direction or by pulling back the pushbutton. In unlocked position, the safety guard is protected against unintentional closing. Lateral emergency exit (ordering suffix -) Emergency exit on the cover side or on the rear side (ordering suffix -D/-U) he safety switchgears are classified according to ISO as type 2 interlocking devices. 2
